To all whom it may concern.'

Beit known that I, LINDLEY KLEINHANS,

a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in a Railway Dump Car, of which the following isa specification.

construction.

The general object of the invention is to provide a construction in conjunction with a dump car' wherebyy the door on either sido of the car which is tilted downwardly into discharging position is automatically extended, and is held in extended position to Aform a delivery chute for the lmaterial in the car.

Another object of the invention is to provide door supporting means of the character'V indicated which'act wholly by gravity, S'o thatthe shifting of centers due to tilting of the car body serves to open and extend the door on the discharge side of the car.

vide a safety lock for preventing undesired opening of the car door on the side of the body which is raised during the dumping operation. Y

Still further objects of the inventlon are to provide readily disengageable connecting means which are applicable to use in the I mechanism of the present invention, anda i door hinge which is so arranged that the doors may be readily lifted from posltion on the oorof the ear body.

In the accompanying drawings Figure 1s an end elevation of adumping car, showing the mechanism of the present invention;

Figure 2 is a side elevation of one end of the car showing the door operating mechanism for the end shown; Figure 3 is an end elevation similar to Figure 1, but showlng 1n full lines the carbody and the door operating mechanism in an intermediate position assumed during the swinging of the car body to dumping position, and showing 1n dotted lines the car body and the door on the dumping side-thereof in fully swung or j dumping position; y.Figure 4 is a fragmentary sectional viewy throu hthe car body,

On this pedestal 2 is a. pivot pin 4 for connection with the supporting lug or block 5 on the under side of the car body 6. Two or more such pivotal connections may be provided for the car body.

Means for locking the car body in carrying position, and for engaging the door oper- S0 ating arms .of the car, comprise brackets 7 and 7a disposed one on each side of the car, and having respectively upwardly extending pedestal arms l8 and 8a. Thei pedestal arm 8 is provided withan aperture 9 arranged to receive a pin 10 on an arm 11. This arm 11 is pivotally mounted on a pin 1bv extending through yoke'12, which is hinged at 13 tothe arm 11 so that the entire member may be broken part wayof its length,

As shown in Figure 7 of the drawings, the pedestal arm 8 and arm 11 are held in mutual engagement by means of the pin 10 passing through the aperture 9 in the pedestal arm 8. Withdrawal of the pin 10 from its engaging aperture is prevented by means of a squared sleeve 14 which slides down over the engaging extremity ofthe arm 11 and a lug 15 on the pedestal arm 8.` To disengage these arms the sleeve 14 .is forced 1 00 upwardly and the pin 10'forced out of engagement with the aperture 9this action belng permitted by the hinged construction of l the arm 11.

Similarly the pedestal arm 8a on the other side of the car is provided with an aperture 9a. for the engagement of a pin 10l carried by the arm 11, the upper extremity of which provides the 'pivotal pin 12, and

whichis similarly hinged at 13. con- 110 struction being identical with that on the other side of the car, is likewisey provided with the sleeve 14a slidable on the arm 11a and engaging a lug 15a on the pedestal arm 8a, which cooperates with the lower portion of the arm 11a.

The pivot pins 16 and 16, mounted in the yoke or pivotal members 12 and 12a of the arms 11 and 11a carry respectively arms 17 and 18 and arms 17a and 131. The arms 18 and 18L are both pivoted on a pin 19 in a strap or bar 20, which extends downwardly y beyond the car body 6. The pivot pin 19 is in diiect alignment with the pivotal connections 4 for the car body. Stop bars 21 and 21a, secured to the endy of the car body, have hooked portions 22 and 2,2a engaging respectively the` under sides of the arms 18 and 18a.

.The car doors 23 and 23a are pivotally secured to the car body 6 by means of hinges indicated generally by the reference numerals 24 and 24aL for the different doors. Each of these hinges comprises a leaf 25, secured to the floor 26 of the car body, and provided with an open ferrule or channel 27. The other leaf 28 is provided with a hinge pin 29 lying in the channel 27. The doors 23 and 23 are provided respectively with the stop bars 30 and 30"L which extend downvcadly beyond the floor 26 of the car vAsi- ms 17 and 17 are pivotally connected by pins 31 and 31a with arms or bars 32 and 32, which are 4secured respectively to the doors 23 and 23a Arcuate straps 33 and 33a may be. desirably provided to serve as additional means for limiting the outward swinging of doors 23 and 23a. These straps are secured to the doors adjacent the upper extremities of the latter, and have @thereon stop lugs 34 and 34a. Staples 35 and 35a overlie the-straps 33 and 33a, and serve asjluimiting means for the lugs 34 and'34a. l

It should be understood that the structure described above is duplicated in identical form for both ends of the car. Since the form and arrangement ofthe parts isfidentical for both ends, the descrlption of the device as applied to one end should be suf-A icient.

AIn Figure 1 of the drawings, the car, and the mechanism of the present invention associated therewith, is shown in level or carrying position. In order to bring the car body and one 0f the doors of' the car into the dumping position shown in Figurel l3, one of the arms 11 or 11a islirstdlsengaged from its corresponding pedestal arm 8 or 8a. As shown in Figure 3, the arm 11a to the right of the drawing is to permit dumping of the tothe left in the drawing.

Disengagement of the pedestal arm 11 disenga ed car on the sgid is effected by forcing sleeve 14a upwardly from engagement with the lug y15". The eiective length of the arm 11a may then be decreased by forcing its parts outwardly at their point of pivotal connection 13a. This permits withdrawal of pin 10 from the orifice 9Z1 in the bracket or pedestal arm 8a. The jointed structure of the arms 11 and 11a is rendered necessary by the fact that the pivot pins 16 and 16a, on which they are mounted, are fixed points in the mechamsm.

lVhen arm 11a has been freed, tilting movement of the car body 6 may be started by applying -any lifting force to that side of the body at which the pedestal arm hasY` been disengaged, by shifting the materialv toward the other side of the body, or by an unequal loading of the car.

During this tilting movement the door on the high side of the car is maintained in closed position by the action of stop bar 21 on the transverse arm18a, this stop bar preventing downward rotation of the arm operating arm 17 with the bar 32 secured to the door 23". Beca-use of this positioning the resultant of the forces tending to swing the door to open position is directed down-l wardly against the engaging lug 22n of the stop bar 21, and movement of the parts for operating the-door is thus positively prevented. On the downward swinging side of the car body,-the change of position of the pivotal center 31 with respect to the piv# o-tal center 16 causes the arm 17 to swing inwardly on its pivo-t 16. The transverse arm 18 is rigid betweenits ` pivotal points 16 and 19. As the door operating arm 17 swings downwardly and inwardly, the door 23 swings around the4 pivotal connection 29 between arm 17 and bar 32 until it assumes a position in line with the floor 26 of the car body, as shown in dotted lines in Figure 3 of the drawings. It is prevented from swinging below the floor line by the engagement of stop bar 30 with the under side of fthe Hoor 26. If the arcuate stops'33 and 33 are likewise provided, further swinging 8a. This is eifecte'd by bringing thev lock-y movement of the body.

stored to horizontaler carrying positionthe arms 1l at both. ends of the car are reconnected to their bracket or pedestal 'arms ing pin 10'rl on each arm into the oritice 9a of its pedestal arm. The sleeve '14i is then forced downwardly over the lug 15av to secure the arm in position'. It shouldbe noted that the device described above is simple in construction and automatic` in operation. It should befurther noted that the arrangement is such as to prevent undesired opening on either door with the car body in horizontal or carrying position, and to prevent undesired opening of the door on the high side of the car body during tilting The stop bars 21 and 21a not only prevent undesired opening of the dooronfthe high the lug on the stop bar on the side which-has been dumped tends to absorb the shock when the parts. on this side of the car assume i their normal or carrying position.
